DQL (Doctrine Query Language) is a object query language which allows
|
|
you to find objects. DQL understands things like object relationships, polymorphism and
|
|
inheritance (including column aggregation inheritance).
|
|
For more info about DQL see the actual DQL chapter.
|

|
|
|
|
Doctrine_Query along with Doctrine_Expression provide an easy-to-use wrapper for writing DQL queries. Creating a new
|
|
query object can be done by either using the new operator or by calling create method. The create method exists for allowing easy
|
|
method call chaining.
|

|
<code type="php">
|
|
// initalizing a new Doctrine_Query (using the current connection)
|
|
$q = new Doctrine_Query();
|
|
|
|
// initalizing a new Doctrine_Query (using custom connection parameter)
|
|
// here $conn is an instance of Doctrine_Connection
|
|
$q = new Doctrine_Query($conn);
|
|
|
|
// an example using the create method
|
|
// here we simple fetch all users
|
|
$users = new Doctrine_Query::create()->from('User')->execute();
